Toxicity of particles derived from combustion of Ethiopian traditional biomass fuels in human bronchial and macrophage-like cells

The combustion of traditional fuels in low-income countries, including those in sub-Saharan Africa, leads to extensive indoor particle exposure. Yet, the related health consequences in this context are understudied. This study aimed to evaluate the in vitro toxicity of combustion-derived particles relevant for Sub-Saharan household environments. Particles (< 2.5 µm) were collected using a high-vol

Safe Transportation of Children With Disabilities and Medical Conditions in Motor Vehicles : Experiences and Perspectives of Australian Health Professionals and Organisations

Providing safe and accessible transportation for children with disabilities and medical conditions can be challenging and complex, as they are particularly vulnerable during road vehicle transportation. Health professionals and organisations play a vital role in supporting families and other involved individuals to ensure their child is transported safely. To obtain a better understanding of the e

European stroke organisation (ESO) guideline on cerebral small vessel disease, part 2, lacunar ischaemic stroke

A quarter of ischaemic strokes are lacunar subtype, typically neurologically mild, usually resulting from intrinsic cerebral small vessel pathology, with risk factor profiles and outcome rates differing from other stroke subtypes. This European Stroke Organisation (ESO) guideline provides evidence-based recommendations to assist with clinical decisions about management of lacunar ischaemic stroke

Wet Twisting in Spinning for Rapid and Cost-Effective Fabrication of Superior Carbon Nanotube Yarns

Carbon nanotubes (CNTs) are promising blocks for building advanced yarns with unique structural and functional attributes. However, the complexity of fabrication and high cost has hindered the widespread adoption of CNT yarns. In this study, a rapid and continuous twisting wet spun yarn strategy to produce highly densified CNT yarns is presented. The method involves effectively dispersing CNTs in

Kvinnors och mäns bonusförföräldraskap

Ett ökande omsorgsgivande från förföräldrar till barnbarn är en signifikant utveckling i Sverige (Bordone et al, 2023; Cantillon et al., 2021) en annan utveckling är att allt fler äldre har bonusbarnbarn, till följd av att de eller deras barn lever i ombildade familjer (Bildtgård & Öberg, 2017). Det intensiva förföräldraskapet utmärks av att bio-förföräldrar idag gör, och förväntas göra, mer o

Modelling realistic microgels in an explicit solvent

Thermoresponsive microgels are polymeric colloidal networks that can change their size in response to a temperature variation. This peculiar feature is driven by the nature of the solvent-polymer interactions, which triggers the so-called volume phase transition from a swollen to a collapsed state above a characteristic temperature. Recently, an advanced modelling protocol to assemble realistic, d

Fluctuating systems under cyclic perturbations : Relation between energy dissipation and intrinsic relaxation processes

This study focuses on fluctuating classical systems in contact with a thermal bath, and whose configurational energetics undergoes cyclic transformations due to interaction with external perturbing agents. Under the assumptions that the configurational dynamics is a stochastic Markov process in the overdamped regime and that the nonequilibrium configurational distribution remains close to the unde

Beyond Average : a-Particle Distribution and Dose Heterogeneity in Bone Metastatic Prostate Cancer

a-particle emitters are emerging as a potent modality for disseminated cancer therapy because of their high linear energy transfer and localized absorbed dose profile. Despite great interest and pharmaceutical development, there is scant information on the distribution of these agents at the scale of the a-particle pathlength. We sought to determine the distribution of clinically approved [223Ra]R

Microwave power harvesting using resonator-coupled double quantum dot photodiode

We demonstrate a microwave power-to-electrical energy conversion in a resonator-coupled double quantum dot. The system, operated as a photodiode, converts individual microwave photons to electrons tunneling through the double dot, resulting in an electrical current flowing against the applied voltage bias at input powers down to 1 fW. The device attains a maximum power harvesting efficiency of 2%,

Effects of certain pre-analytical factors on the performance of plasma phospho-tau217

Introduction: Pre-analytical factors can cause substantial variability in the measurements of cerebrospinal fluid (CSF) and plasma biomarkers of Alzheimer’s disease (AD). However, their effects on the performance of one of the most promising plasma AD biomarkers, phosphorylated tau (p-tau)217, are not known. Methods: We included 50 amyloid-β positive (Aβ+) and 50 Aβ− participants from the Swedish

Swedish musculoskeletal researchers view on a collaborative network and future research priorities in Swedish healthcare

Background: Musculoskeletal disorders (MSK) are a global burden causing significant suffering and economic impact. Systematic identification and targeting of research questions of highest interest for stakeholders can aid in improving MSK disorder knowledge and management. Objective: To obtain Swedish MSK researchers' opinions and views on a collaborative Swedish MSK network (SweMSK) and identify

Mass spectroscopy reveals compositional differences in copepodamides from limnic and marine copepods

Marine copepods, the most abundant animals in the global ocean, imprint their surrounding waters with chemical cues, called copepodamides. Copepodamides induce defensive traits such as toxin production, bioluminescence, and colony size plasticity in a variety of marine phytoplankton. The role of copepodamides in freshwater ecosystems is, however, unknown. Here we report the consistent presence of

Angle estimation using mmWave RSS measurements with enhanced multipath information

mmWave communication has come up as the unexplored spectrum for 5G services. With new standards for 5G NR positioning, more off-the-shelf platforms and algorithms are needed to perform indoor positioning. An object can be accurately positioned in a room either by using an angle and a delay estimate or two angle estimates or three delay estimates. We propose an algorithm to jointly estimate the ang

Graphite oxide by “chlorate route” oxidation without HNO3 : Does acid matter?

Very strong difference in many properties is well documented for graphite oxides (GtO) synthesized by Brodie (BGO) and Hummers (HGO) methods. The difference is typically assigned to the type of oxidant (chlorates or KMnO4, respectively). However, not only oxidants but also acids used in these methods are different. It is still unclear which of the different properties of GtO are dependent on the o
